System for enhanced authentication using non-fungible tokens (NFTs)

ABSTRACT

Enhanced authentication at resource event apparatuses of a card device and, in some instances, the user of the card device. Card device-specific Non-Fungible Tokens (NFTs) are generated and, in some instance, user credential-specific NFTs are generated. The NFTs are stored within a distributed ledger of a distributed trust computing network, which provides verification as the uniqueness and authenticity of the NFTs. Once a resource event is initiated at a resource event apparatus, card device-related information and, in some instance, user credential-related information is received, and the information is compared to the corresponding NFT as a means of authenticating the card device and, in some instances, the card device and the linked user of the card device. As a result, the use of imitation card devices is prevented and, in some instances, the identity of the user of the card device is authenticated and deemed to be linked to the card device.

FIELD OF THE INVENTION

The present invention is generally related to network authentication and, more specifically, authenticating a card device and the user of the card device at resource event apparatuses through the use of card device non-fungible tokens (NFTs) and user identification credential NFTs.

BACKGROUND

The nefarious use of skimmer devices at Automated Teller Machine (ATM), point-of-sale (POS) devices and the like has become more prevalent. A skimmer device is disguised to look like part of the ATM or POS devices and is used to read the information stored on the card device as it is inserted into or swiped at the ATM or POS device. In addition, skimmer devices have been employed that have the capability to capture the user's Personal Identification Number (PIN). Once the wrongdoer has possession of the card device information and/or PIN, the wrongdoer may generate imitation card devices that can readily be user by the wrongdoers at the ATM or POS device. Currently, minimal to no means exist to be able to detect imitation card devices once they are inserted into or swiped at a resource event apparatus (e.g., card reader device).

Moreover, user authentication at a resource event apparatus, such as an ATM, POS device or the like, typically occurs by the user providing authentication credentials, such as a Personal Identification Number (PIN), a signature or the like. However, such authentication credentials may easily be either wrongfully possessed or replicated by a wrongdoer.

Therefore, a need exists to develop systems, methods, computer program products and the like that provide for a heightened level of authentication at a resource event apparatus, such as ATMS, POS devices and the like. Specifically, the authentication mechanisms should provide for verifying the authenticity of the card device itself to prevent against the use of imitation/bogus card devices at resource event apparatuses. Moreover, the authentication mechanisms should provide for verifying the identity of the card device user beyond conventional means, such as user presentation of authentication credentials, such as a PIN, phot identification, signature or the like.

BRIEF SUMMARY

The following presents a simplified summary of one or more embodiments of the invention in order to provide a basic understanding of such embodiments. This summary is not an extensive overview of all contemplated embodiments and is intended to neither identify key or critical elements of all embodiments, nor delineate the scope of any or all embodiments. Its sole purpose is to present some concepts of one or more embodiments in a simplified form as a prelude to the more detailed description that is presented later.

Embodiments of the present invention address the above needs and/or achieve other advantages by providing for enhanced authentication of the card device and, in some embodiments of the invention, the user of the card device at resource event apparatuses, such as Automated Teller Machines (ATMs), Point-of-Sale (POS) devices and the like. Specifically, the invention relies on generating card device-specific Non-Fungible Tokens (NFTs) and, in some embodiments of the invention user credential-specific NFTs. Since the NFTs are stored within a distributed ledger of a distributed trust computing network, the NFTs are verified, through consensus reached by nodes, as being authentic and unique.

Card device-specific NFTs may be generated using, as the input to the hash algorithm(s), one or more of (i) an image of at least one facing of the card device, (ii) unique computer-readable indicia displayed on a portion of a facing of the card device and/or (iii) card-related information (e.g., information accessible through inserting or swiping the card device at a resource event apparatus), such as user identifier, account identifier or the like. Subsequently, when the card is inserted into or swiped at a resource event apparatus, the card device-related information used to generate the card-device-specific NFT is received by performing at least one (i) capturing or receiving an image of the facing of card device, (ii) reading the unique computer indicia and/or (iii) reading or accessing the card-related information stored on an embedded chip or magnetic strip of the card device or a digital wallet of a mobile device in possession of the user. Once the card device-related information is received at the resource event apparatus, the distributed trust computing network is accessed to determine if a match exists between device-related information and the card device-specific NFT. If a match is determined to exist, the card device is deemed to be authenticated, while if no match is determined to exist, the user is denied from processing further events at the resource event apparatus.

In further embodiments of the invention, the authentication is a dual authentication of both the card device and the user of the card device. In such embodiments of the invention, once the card device is assigned to a user, a user credential-specific NFT is generated using, as the input to the hash algorithm(s), one or more of (i) an image of the user, (ii) an image of a facing of user credentials (e.g., a driver's license, passport or the like) and/or (iii) information displayed on the user credentials (e.g., name, address, driver's license number, passport number or the like) and linked to the card device-specific NFT. Subsequently, at the resource event apparatus, user-credential information is received by performing one or more of (i) capturing or receiving an image of the user, (ii) capturing or receiving an image of a facing of the user credentials and/or (iii) receiving user credential information. Once the card device has been authenticated (i.e., once a determination is made that the card-device information matches the card device-specific NFT), the distributed trust computing network is accessed to determine if a match exists between the user credential information and a user credential-specific NFT (i.e., whether a user credential-specific NFT exists for the user credential information) and, if so, whether the user credential-specific NFT is linked to the card-device-specific NFT. If a match and link is determined to exist, the user is deemed to be authenticated and allowed to process/conduct resource events and the resource event apparatus, while if no match or no link is determined to exist, the user is denied from processing further events at the resource event apparatus.

The system includes a distributed trust computing network including a plurality of decentralized nodes, each decentralized node configured to store at least a portion of a distributed ledger including a plurality of data blocks.

Embodiments of the present invention are described below with reference to flowchart illustrations and/or block diagrams of methods or systems. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a particular machine, such that the instructions, which execute by the processor of the computer or other programmable data processing apparatus, generate mechanisms for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks.

As the phrase is used herein, a processor may be “configured to” perform or “configured for” performing a certain function in a variety of ways, including, for example, by having one or more general-purpose circuits perform the function by executing particular computer-executable program code embodied in computer-readable medium, and/or by having one or more application-specific circuits perform the function.

“Computing platform” or “computing device” as used herein refers to a networked computing device within the computing system. The computing platform may include a processor, a non-transitory storage medium (i.e., memory), a communications device, and a display. The computing platform may be configured to support user logins and inputs from any combination of similar or disparate devices. Accordingly, the computing platform includes servers, personal desktop computer, laptop computers, mobile computing devices and the like.

Thus, systems, apparatus, and methods are described in detail below that provide for enhanced authentication, at a resource event apparatus (e.g., ATM, POS device or the like) of the card device and, in some embodiments of the invention, the user of the card device. Specifically, the invention relies on generating card device-specific Non-Fungible Tokens (NFTs) and, in some embodiments of the invention user credential-specific NFTs. Since the NFTs are stored within a distributed ledger of a distributed trust computing network, the NFTs are verified, through consensus reached by nodes, as being authentic and unique.

Card device-specific NFTs may be generated using, as the input to the hash algorithm(s), one or more of (i) an image of at least one facing of the card device, (ii) unique computer-readable indicia displayed on a portion of a facing of the card device, and/or (iii) card-related information (e.g., information accessible through inserting or swiping the card device at a resource event apparatus), such as user identifier, account identifier or the like. Subsequently, when the card is inserted into or swiped at a resource event apparatus, the card device-related information used to generate the card-device-specific NFT is received by performing at least one (i) capturing or receiving an image of the facing of card device, (ii) reading the unique computer indicia and/or (iii) reading or accessing the card-related information stored on an embedded chip or magnetic strip of the card device or a digital wallet of a mobile device in possession of the user. Once the card device-related information is received at the resource event apparatus, the distributed trust computing network is accessed to determine if a match exists between device-related information and the card device-specific NFT. If a match is determined to exist, the card device is deemed to be authenticated, while if no match is determined to exist, the user is denied from processing further events at the resource event apparatus.

In further embodiments of the invention, the authentication is a dual authentication of both the card device and the user of the card device. In such embodiments of the invention, once the card device is assigned to a user, a user credential-specific NFT is generated using, as the input to the hash algorithm(s), one or more of (i) an image of the user, (ii) an image of a facing of user credentials (e.g., a driver's license, passport or the like) and/or (iii) information displayed on the user credentials (e.g., name, address, driver's license number, passport number or the like). In addition, the user credential-specific NFT is linked to the card device-specific NFT (i.e., the data block within the distributed ledger that contains the user credential-specific NFT is linked to the data block within the distributed ledger that contains the card device-specific NFT). Subsequently, at the resource event apparatus, user-credential information is received by performing one or more of (i) capturing or receiving an image of the user, (ii) capturing or receiving an image of a facing of the user credentials and/or (iii) receiving user credential information. Once the card device has been authenticated (i.e., once a determination is made that the card-device information matches the card device-specific NFT), the distributed trust computing network is accessed to determine if a match exists between the user credential information and a user credential-specific NFT (i.e., whether a user credential-specific NFT exists for the user credential information) and, if so, whether the user credential-specific NFT is linked to the card-device-specific NFT. If a match and link is determined to exist, the user is deemed to be authenticated and allowed to process/conduct resource events and the resource event apparatus, while if no match or no link is determined to exist, the user is denied from processing further events at the resource event apparatus.

Referring to FIG. 1 , a schematic diagram of an exemplary distributed trust computing network 100 is depicted, in accordance with embodiments of the present invention. The distributed trust computing network 100, in other instances referred to a blockchain network, is a distributed database that maintains, e.g., a list of data records, or the like. In specific embodiments of the invention the data records may include non-fungible tokens (NFTs) that serve to verify the authenticity card devices and users of card devices. The security of the data maintained within the trust network is enhanced by the distributed nature of the network. The distributed trust computing network 100 typically includes several decentralized nodes 110, which may be one or more systems, machines, computers, databases, data stores or the like operably connected with one another. In some instances, each of the nodes 110 or multiple nodes 110 are maintained by different entities. A distributed trust computing network 100 typically works without a central repository or single administrator.

A distributed trust computing network 100 provides numerous advantages over traditional storage networks/databases. A large number of the decentralized nodes 110 of a trust network may reach a consensus regarding the validity of resources or data maintained with a block of the distributed trust computing network, in the context of the present invention the validity of the hardware component and/or device (i.e., the validity of the measured authenticity characteristics).

The distributed trust computing network 100 typically has two primary types of records. The first type is the record type, which consists of the actual data, in this case an NFT, stored in a data block 130 within a distributed register/ledger 120. The second type is the block type, which are records that confirm when and in what sequence certain events became recorded as part of the distributed trust computing network. Records, such as a code change file segment records, and the events associated therewith are generated by participants using the distributed trust computing network in its normal course of business, for example, when code change file segment is determined, a data block(s) 130 is generated by users known as “miners” who use specialized software/equipment to generate data blocks 130. Holders of a data block 130 of the distributed trust computing network 100 agree to store the data block 130 within the distributed trust computing network 100 and the related data blocks 130 are passed around to various nodes 110 of the distributed trust computing network 100. A “valid” data block 130 or related event is one that can be validated based on a set of rules that are defined by the particular system implementing the distributed trust computing network 100. For example, in the case of card devices and users of card devices verification, a valid data block is one that stores an NFT which serves to verify the authenticity of the corresponding card device or user of the card device.

A distributed trust computing network 100 is decentralized—meaning that a distributed register/ledger 120 (i.e., a decentralized register/ledger) is maintained on multiple nodes 110 of the distributed trust computing network 100. In this regard, one node 110 in the distributed trust computing network 100 may have a complete or partial copy of the distributed register/ledger 120 or set of records and/or blocks 130 on the distributed trust computing network 100. Transactions/events (i.e., newly presented NFTs) are initiated at a node 110 of a distributed trust computing network 100 and communicated to the various other nodes 110 of the distributed trust computing network 100 for validation purposes. Any of the nodes 110 can validate the content of a data block 130 or an associated event, add the data block 130 and/or the contents of the data block 130 to its copy of the distributed register/ledger 120, and/or broadcast the detail/data of the data block 130, its associated validation (in the form of a data block 130) and/or other data to other nodes 130.

Referring to FIG. 2 , a schematic/block diagram is presented of a system 200 for verifying the authenticity of a card device using Non-Fungible Tokens (NFTs), in accordance with embodiments of the present invention. The system 200 is implemented within a distributed communication network 210 that may include the Internet, one or more intranets, one or more cellular networks, one or more short-range wireless networks or the like.

The system includes a distributed trust computing network 100 including a plurality of decentralized nodes 110. Each decentralized node 110 having a memory (not shown in FIG. 2 ) and at least one processing device (not shown in FIG. 2 ). The memory of the decentralized nodes 110 is configured to store a distributed ledger 120 that includes a plurality of data blocks 130.

The system 100 additionally includes a first computing platform 300 having a first memory 302 and at least one first processing device 304 in communication with first memory 302. First memory 302 stores Non-Fungible Token (NFT) generation sub-system 310 that includes first instructions 320, which are executable by at least one of the first processing devices 304. First instructions 320 are configured to, in response to producing a card device 340, generate a first NFT 330 associated with the card device 340 (i.e., a card device NFT 330). The card device 340 may include any card device having a magnetic strip or embedded chip that stores information. For example, the card device 340 may be a debit card device or a credit card device that stores user account information or the magnetic strip or embedded chip and is used to conduct financial transactions. As discussed infra., in specific embodiments of the invention, the first NFT 330 may be generated using, as at least a portion of the input to one or more hash algorithms, one or more of (i) an image(s) of one or more facings of the card device, (ii) computer-readable indicia displayed on a portion of a facing of the card device and/or (iii) information stored on the magnetic strip or embedded chip of the chip device and/or the like.

Once the first NFT 330 has been generated, the first NFT 330 is communicated to the distributed trust computing network 100. In response to the distributed trust computing network 100 receiving the first NFT 330, the decentralized nodes 110 of the trust computing network 100 are configured to reach a consensus on the first NFT 330 to verify the authenticity of the NFT and generate a first data block 130 within the distributed ledger 120 that stores the verified first NFT 330.

System 200 additionally includes a second computing platform 400, which may include an Automated Teller Machine (ATM), Point-of-Sale (POS) device, as well as back-end/network apparatus, such as application servers or the like. Second computing platform 400 has a second memory 402 and at least one second processing device 404 in communication with second memory 402. Second memory 402 stores authentication sub-system 410 that includes second instructions 420, which are executable by at least one of the second processing devices 404. Second instructions 420 are configured to, in response to a user presenting the card device 340 at a resource event apparatus, receive first NFT-related information 430 from at least one of (i) the card device 340 and/or (ii) a digital wallet/mobile device of the user. In specific embodiments of the invention, presentation of the card device 340 at a resource event apparatus includes, inserting, swiping or making wireless contact with an Automated Teller Machine (ATM), Point-of-Sale (POS) device or the like. In other specific embodiments of the invention, receiving the first NFT-related information 430 may include at least one of (i) capturing or receiving an image of a facing of the card device 340, (ii) reading the computer-readable indica displayed on a facing of the card device 340, and/or (iii) receiving short-range wireless communication of the first NFT 330 stored in a digital wallet on the user's mobile communication device.

In response to receiving first NFT-related information 430, second instructions 420 are further configured to determine whether the first NFT-related information 430 matches the first NFT 330. Such a determination may be made by accessing the distributed trust computing network 100 or, in other embodiments of the invention, the corpus of first NFTs may have been previously downloaded/communicated to the second computing platform 400, thus, obviating the need to access to the distributed trust computing network 100. In response to determining that the first NFT-related information 430 does match the first NFT 330, second instructions 420 are configured to deem the card device 340 to be authenticated 440 (i.e., the card device is not an imitation card device). In specific embodiments of the invention, such authentication may result in authorization for the user to conduct resource events at the resource event apparatus, while in other instances, as discussed infra., further authentication may be required (such as authentication of the user and/or verification that the user is linked to the card device). In response to determining that the first NFT-related information 430 does not match the first NFT 330, second instructions 420 are configured to deny 450 further processing of any resource events at the resource event apparatus. For example, in specific embodiments of the invention, a user may be denied from conducting transactions at the ATM, POS device or the like.

Referring to FIG. 3 , a schematic/block diagram is presented of an alternate system 220 for verifying the authenticity of a card device and authenticating the user of the card device (i.e., dual authentication) using Non-Fungible Tokens (NFTs), in accordance with embodiments of the present invention. The system 220 includes the distributed trust computing network 100, first computing platform 300 and second computing platform 400 discussed in relation to FIG. 2 . In the system 220, first instructions 320 of NFT generation sub-system 310 are further configured to, in response to issuing the card device 340 to a user, generate a second NFT 350 associated with user identification 360 (i.e., a user identification NFT) and linked 370 to the first NFT 330. As discussed infra., in specific embodiments of the invention, the second NFT 350 may be generated using, as at least a portion of the input to one or more hash algorithms, one or more of (i) an image(s) of the user, (ii) an image of user identification credential (e.g., driver's license, passport or the like) and/or (iii) information displayed on the user identification credential (e.g., name, address, driver's license number, passport number and the like) and/or the like. Linking of the second NFT to the first NFT ensures that the card device 340 is being used at the resource event apparatus by an individual that has been verified, by the distributed trust computing network, as an authorized user of the card device 340.

Further, in system 220, second instructions 420 of authentication sub-system 410 are configured to, receive second NFT-related information 460 from at least one of (i) the user and/or (ii) a digital wallet/mobile device of the user. In specific embodiments of the invention, receiving the second NFT-related information 460 may include at least one of (i) capturing or receiving an image of the user, (ii) capturing or receiving an image of the user identification credential, and/or (iii) receiving short-range wireless communication of the second NFT 330 stored in a digital wallet 432 on the user's mobile communication device 466 and/or user identification credential information 396. In response to determining that the first NFT-related information 430 matches the first NFT 340 (i.e., in response to authenticating the card device 340), second instructions 420 are further configured determine whether the second NFT-related information 460 matches the second NFT 350 and, if so, whether the second NFT 350 is linked to the first NFT 330 (i.e., linkage verification 470). In response to determining that the second NFT-related information 460 matches the second NFT 350 and the second NFT 350 is linked to the first NFT 330, second instructions 420 are configured to provide the user resource event authorization 480 to conduct resource events at the resource event apparatus. However, in response to determining either that the first NFT-related information 430 does not match the first NFT 340 or the second NFT 350 is not linked to the first NFT 330, second instructions 420 are further configured determine whether the second NFT-related information 460 matches the second NFT 350 and, if so, whether the second NFT 350 is linked to the first NFT 330 (i.e., linkage verification 470). In response to determining that the second NFT-related information 460 matches the second NFT 350 and the second NFT 350 is linked to the first NFT 330, second instructions 420 are configured to deny 450 the user from performing resource events at the resource event apparatus.

Thus, the communication module may include the requisite hardware, firmware, software and/or combinations thereof for establishing and maintaining a network communication connection with one or more systems, platforms, networks, or the like.

Second memory 402 of second computing platform 400 stores authentication sub-system 410 that includes second instructions 420 which are configured to, in response to presenting the card device at a resource event apparatus, receive first NFC-related information at the resource event apparatus from one or more of (i) the card device 340 and/or (ii) the user's digital wallet 432/mobile device 466.

In response to receiving first NFT-related information 430, second instructions 420 are further configured to determine whether the first NFT-related information 430 matches the first NFT 330. Such a determination may be made by accessing the distributed trust computing network 100 or, in other embodiments of the invention, the corpus of first NFTs may have been previously downloaded/communicated to the second computing platform 400, thus, obviating the need to access to the distributed trust computing network 100. In response to determining that the first NFT-related information 430 does match the first NFT 330, second instructions 420 are configured to deem the card device 340 to be authenticated 440 (i.e., the card device is not an imitation card device). In specific embodiments of the invention, such authentication may result in authorization for the user to conduct resource events at the resource event apparatus, while in other instances, as discussed infra., further authentication may be required (such as authentication of the user and/or verification that the user is linked to the card device). In response to determining that the first NFT-related information 430 does not match the first NFT 330, second instructions 420 are configured to deny 450 further processing of any resource events at the resource event apparatus.

Further, second instructions 420 are configured to receive second NFT-related information 460 from at least one of (i) the user 462 and/or (ii) a digital wallet 432/mobile device 466 of the user. In specific embodiments of the invention, receiving the second NFT-related information 460 may include at least one of (i) capturing or receiving an image 392 of the user 462, (ii) capturing or receiving an image 394 of the user identification credential, and/or (iii) receiving short-rang wireless communication of the second NFT 330 stored in a digital wallet on the user's mobile communication device.

In response to determining that the second NFT-related information 460 matches the second NFT 350 and the second NFT 350 is linked to the first NFT 330, second instructions 420 are configured to provide the user resource event authorization 480 to conduct resource events at the resource event apparatus. However, in response to determining either that the first NFT-related information 430 does not match the first NFT 340 or the second NFT 350 is not linked to the first NFT 330, second instructions 420 are further configured determine whether the second NFT-related information 460 matches the second NFT 350 and, if so, whether the second NFT 350 is linked to the first NFT 330 (i.e., linkage verification 470).

Referring to FIG. 6 , a flow diagram is depicted of a computer-implemented method 500 for authenticating a card device at a resource event apparatus using Non-Fungible Tokens (NFTs), in accordance with embodiments of the present invention. At Event 510, in response to manufacturing each of a plurality of components for a hardware device and measuring authenticity characteristics for each of the plurality of components, a component-based NFT is generated that uses, as the input to the hash algorithm, at least one component identifier and the measured authenticity characteristics of the corresponding component. As previously discussed, the authenticity characteristics include any characteristic of the hardware component that is measurable and is associated with component integrity (i.e., ensuring that the component is in a certifiable-state and has not otherwise been altered/tampered). In specific embodiments of the invention, the measurements may include, but are not limited to, electro-magnetic characteristics, heat attributes/characteristics, physical characteristics, such weight, dimensions and the like. To ensure the integrity of the component the authenticity characteristics should be measured as soon as possible after the component has manufactured and conducted in a controlled environment.

In response to generating the component-based NFTs, at Event 520, the component-based NFTs are communicated to a distributed trust computing network. The distributed trust computing network comprises a plurality of decentralized having a memory and one or more processing devices in communication with the memory. The memory of the decentralized nodes stores one or more distributed ledgers, which comprise a plurality of data blocks.

In response to the distributed trust network receiving the component-based NFTs, at Event 530, the authenticity and certifiable state of the NFTs, and, thus, the component is verified by the decentralized nodes of the distributed trust computing network reaching a consensus on the NFT. In response to verifying the authenticity and certifiable state of the NFTs, at Event 540, data blocks are generated within the distributed ledger of the distributed trust computing network that store a corresponding one of the verified NFTs. In this regard, the distributed ledger provides hardware integrity verification and traceability (i.e., chain-of-custody) when the components are subsequently assembled into sub-assemblies or end products (i.e., hardware devices). As previously discussed, the computer-implemented method may further include events for generating NFTs for subsequent sub-assemblies and/or the hardware device that includes the components. In such embodiments of the method, the generation of NFTs may use, as inputs to the hash algorithm(s), at least one identifier of the sub-assembly or hardware device and measured authenticity characteristics of the sub-assemblies and/or hardware device/end product.

Referring to FIG. 6 , a flow diagram is depicted of a computer-implemented method 500 for authenticating a card device at a resource event apparatus using Non-Fungible Tokens (NFTs), in accordance with embodiments of the present invention. At Event 510, in response to producing a card device configured for executing resource events, a first Non-Fungible Token (NFT) is generated that is associated with the card device. Is previously discussed, the first NFT may be generated using, as at least a portion of the input to one or more hash algorithms, one or more (i) an image of a facing of the card device, (ii) computer-readable indicia displayed on a facing the card device, and/or (iii) information stored on the card device or the like. At Event 520, the first NFT is communicated to a distributed trust computing network that has decentralized nodes, which are configured to store at least a portion of a distributed ledger that comprises data blocks.

At Event 530, in response to the distributed trust computing network receiving the first NFT, the authenticity of the first NFT is verified through a consensus reached by the decentralized nodes and a data block is generated within the distributed ledger that stores the verified first NFT.

At Event 540, in response to a user presenting the card device at a resource event apparatus (e.g., ATM, POS device or the like), first NFT-related information is received at the resource event apparatus from (i) the card device and/or (ii) a digital wallet/mobile device of the user. As previously discussed, presenting the card device at the resource event apparatus may include inserting, swiping or short-range wirelessly contacting (e.g., NFC or the like) the card device at the resource event apparatus. Receiving the first NFC-related information may include at least one of (i) capturing or receiving an image of the card device, (ii) reading the computer-readable indicia, (iii) receiving data stored on the card device or the first NFC from a digital wallet or the mobile device or the like.

At Event 550, a determination is made as to whether the first NFC-related information matches a first NFT stored either on the distributed ledger of the distributed trust computing network or stored locally at the resource event apparatus (e.g., ATM, POS device or the like). In response to determining that the first NFC-related information matches a first NFT, at Event 560, the card device is deemed to be authenticated. Alternatively, in response to determining that the first NFC-related information does not match a first NFT, at Event 570, the user is denied/prohibited from conducting any resource events at the resource event apparatus.

Referring to FIG. 7 , a flow diagram is presented of a method 600 for authenticating a card device and a used of the card device using NFTs, in accordance with embodiments of the present invention. At Event 602, a card device is produced/manufactured that is configured for performing resource events (e.g., transactions) at resource event apparatus (e.g., ATM, Pos device or the like). In response to producing/manufacturing the card device, at Event 604, a card device NFT is generated. The card device NFT is generated using, as at least a portion of the input to one or more hash algorithms, one or more of (i) an image of one or more facings of the card device, (ii) computer-readable indicia displayed on a facing of the card device, and/or (iii) information stored on the card device and/or the like. At Event 606, the card device NFT is communicated to a distributed trust computing network.

In response to the distributed trust computing network receiving the card device NFT, at Event 608, an authenticity of the card device NFT is verified by consensus being reached amongst a plurality of decentralized nodes that make up the distributed trust computing network and, at Event 610, the verified card device NFT is stored as a data block within a distributed ledger of the distributed trust computing network.

At Event 612, the card device is issued to a user and, in response at Event 614, a user identification NFT is generated and linked to the card device NFT. The user identification NFT is generated using, as at least a portion of the input to one or more hash algorithms, one or more of (i) an image of the user, (ii) an image of user identification credentials (e.g., driver's license, passport or the like) and/or (iii) information displayed on the user identification credentials and/or the like. At Event 616, the user identification NFT is communicated to a distributed trust computing network.

In response to the distributed trust computing network receiving the use identification NFT, at Event 608, an authenticity of the user identification NFT is verified by consensus being reached amongst a plurality of decentralized nodes that make up the distributed trust computing network and, at Event 610, the verified user identification NFT is stored as a data block within a distributed ledger of the distributed trust computing network.

At Event 618, the card device is presented at a resource event apparatus (e.g., ATM, POS device or the like) and, in response, at Event 620, card device NFT-related information is received at the resource event apparatus from one or more of (i) the card device and/or (ii) the user's digital wallet/mobile device. As previously discussed, the card device NFT-related information may be received by (i) capturing or receiving an image of the card device, (ii) reading the computer-readable indicia displayed on the card device, (iii) receiving, via wireless transmission (NFC or the like), card device information and/or the card device NFC from the user's digital wallet/mobile device. At Event 622, the distributed trust computing network is accessed and, at Decision 624, a determination is made as to whether the card device NFT-related information matches the card device NFC. If the determination is made that the card device NFT-related information does not match any of the card device NFCs stored on the distributed ledger of the distributed trust computing network, at Event 626, the user is denied from performing resource events at the resource event apparatus.

If the determination is made that the card device NFT-related information does not matches any of the card device NFCs stored on the distributed ledger of the distributed trust computing network, at Event 628, user identification NFT-related information is received at the resource event apparatus from one or more of (i) the user and/or (ii) the user's digital wallet/mobile device. It should be noted that the user identification NFT-related information may be received prior to the determination that the card device NFT-related information does not matches any of the card device NFCs. At Event 622, the distributed trust computing network is accessed and, at Decision 630, a determination is made as to whether the user identification NFT-related information matches any of the user identification NFC. If the determination is made that the user identification NFT-related information does not match any of the user identification NFCs stored on the distributed ledger of the distributed trust computing network, at Event 626, the user is denied from performing resource events at the resource event apparatus.

If the determination is made that the user identification NFT-related information does match a user identification NFC stored on the distributed ledger of the distributed trust computing network, at Decision 632, a determination is made as to whether the matched user identification NFC is linked to the card device NFC. If the user identification NFC is determined not to be linked to the card device NFC, at Event 626, the user is denied from performing resource events at the resource event apparatus. If the user identification NFC is determined to be linked to the card device NFC, at Event 634, the user is authorized to perform resource events at the resource event apparatus.

Thus, as described in detail above, present embodiments of the invention include systems, methods, computer program products and/or the like for enhanced authentication of the card device and, in some embodiments of the invention, the user of the card device at resource event apparatuses. Specifically, the invention relies on generating card device-specific Non-Fungible Tokens (NFTs) and, in some embodiments of the invention user credential-specific NFTs. Since the NFTs are stored within a distributed ledger of a distributed trust computing network, the NFTs are verified, through consensus reached by nodes, as being authentic and unique. Once a resource event is initiated at a resource event apparatus, card device-related information and, in some embodiments, user credential-related information is received, and the information is compared to the corresponding NFT as a means of authenticating the card device and, in some embodiments, the card device and the linked user of the card device. As a result, the present invention prevents the use of imitation card devices and authenticates the identity of the user of the card device is ensures that the user is verifiably linked to the card device.

Those skilled in the art may appreciate that various adaptations and modifications of the just described embodiments can be configured without departing from the scope and spirit of the invention.
